At the far end of Llanbedrog beach lies Carreg y Defaid and is best reached along the beach, having explored the excellent rock pools below Mynydd Tir Y Cwmwd and admired the beach huts tucked up to the undercliff. Carreg y Defaid is a small offshore island with an associated headland, both formed from hard volcanic rocks punctuating the softer sedimentary cliffs. A fragment of poor coastal heathland occurs on the headland visited by Linnet and Stonechat. Around the headland there are low rocky cliffs with sparse lichens including the bright orange Maritime Sunburst Lichen and the Black Tar Lichen. The boulders around the headland and further to the east have a relatively low covering of Bladder Wrack. Sea watching is perhaps best in winter for seabirds and roosting shorebirds. A flock of Golden Plover frequents adjacent flooded fields.
